HMR is not working with real physical Android/iOS device - DevServer Not Connected

We are encountering the following issue after installing the app on a physical Android device:

- HMR (Hot Module Replacement) is not working.
- Changes are reflected only after manually killing and reopening the app.

However, when the app is installed on an emulator/simulator, HMR works as expected.

**Note:**
The DevTools console displays the following warning:

`Disconnected from the Dev Server: failed to connect to /10.0.2.2 (port 8081) from /192.168.X.X (port 49638) after 10000ms`

Configurations:
- "react-native": "0.79.3"
- "@callstack/repack": "5.1.2"

We've also tried ensuring both the physical device and the development machine are on the same Wi-Fi network, and attempted connecting via localhost:8081, but the issue persists.

Could you please advise how we can resolve this issue for the physical device?

No files or tests are named; start with the reported Dev Server warning and the React Native/Re.Pack development-server configuration for physical devices. Reproduce on a real Android or iOS device, compare it with the emulator or simulator setup, and consider the issue done when HMR reconnects and reflects changes without restarting the app.
